It is known to build up the checkerwork oi regenerators with square hollow bricks, such bricks having several long square gas ducts formed by cross walls, and longitudinal side walls 5 projecting beyond the cross walls for the purpose of forming a hollow space which connects all gas duets with each other, the side walls being further provided with ribs running parallel to the cross walls, when the checker brickwork is built up. These ribs fix the distance between adjacent checker bricks and the brickwork confining the heat storage space. In the checker brickwork oi long-stretched regenerators, f. i. of the socalled cross regenerators for gas and coke producing chamber ovens continuous horizontal spaces are formed on thefull length of the regenerator by the hollows in the cross walls.

The invention has for its aim to divide by the bricks-themselves regenerators with vertical flow 2g and built up of such checker bricks into several vertical gas spaces, isolated from each other.

For this purpose the horizontal spaces running in the longitudinal direction of the regenerator and formed by the hollows of the cross walls'in the 25 checker bricks are interrupted. This is done in the following way: While the longitudinal side walls of most of the checker bricks are extended by rib-like projections so that they project beyond the cross walls, the end cross wall of several 33 bricks is continued over the full length in upward direction of the longitudinal side walls; the bricks are placed one on top of the other in such away that the continued end cross walls stand one on top of the other forming vertical division walls 35 which extend over the iullheight of the regenerator, dividing the regenerator into several vertical ducts which are isolated one from the other.

The drawing shows reg'enerators for a battery of horizontal gas and coke producing chamber ovens and parts thereof. In this drawing- 5 Fig. 3a; is a vertical central longitudinal section through a top row regenerator brick;

. Fig. 3b is an end view;

Fig. 3c is a plan view of the brick shown in Fig. 3e; and

.5 Fig. ,Sd is a section taken similarly to Fig. 3a,

showing a portion of the brick on a larger scale.

Between the coking chambers a there are the heating walls divided into vertical heating fiues b which are connected with air regenerator c and c and gas regenerator d and'd' arranged under- 5 neath the heating flues b through ducts e and i. From each pair of twin-fines the up-burning flue is connected with two regenerators for preheating gas and air respectively and the downburning fiue is connected with two regenerators 10 for receiving the waste heat. When the regenerator group 0, d is working for heating gas and air respectively, the two adjacent regenerator groups 0' and d are supplied with waste heat and as shown vice versa. 15

The rcgenerators are filled with checker Work asshown in Figs. 1 and 2. One of the checker bricks used in the top layer or row of regenerator checker bricks is shown in Figs. 3a to 3d. The side walls 12 of each brick form with the cross 20 walls h vertical gas ducts of rectangular section. On the bottom of the brick, the side walls 11. vertically project over the cross walls h (Fig. 3b); whereby between two layers or superposed rows of checker bricks, horizontal hollow spaces in the longitudinal direction of the regenerator are formed (Figs. 2a and 2b). In order to subdivide these hollow spaces, the one outer cross wall Ic of some of the bricks has the same height as the side walls 12. The walls is of the bricks in the top row project upwardly over the longitudinal side walls (Figs. 3a and 3b) and reach to the top of the regenerator spaces (Figs. 2a. and 2b) in order to form separate regenerator sections and completely isolate the vertical gas ducts of each section from those of another section.

As shown in Figs. 2a and 2b cross walls lc are provided on some of the bricks in such number that a separate regenerator section always corre- 0 sponds to an individual heating flue. While a gas regenerator is supplying heat to each second heating fiue alternately in one or the other of two adjacent heating walls an air regenerator is only connected with every second heating flue of one heating wall. The sections into which the regenerators are subdivided by means of the cross walls It therefore have in the air regenerators c and 0' double the length of those in the gas regenerators d and 11.

There is known a procedure of removing regenerator'checker bricks by means of a carrying plate provided with a wedge at its front part which is pushed under the cross walls of the In order to follow the same procedure in removing the bricks provided in accordance with reverse way, so that the cross walls is are at the ends of the bricks which face the open end of the regenerator. In such case for the removal of said bricks by the carrying plate procedure, spaces m are provided in the walls k, as shown in Figs. 3a and 311, each such space including a portion leading into the wall 7c from the outer side of the latter, and including a portion extending laterally away from the first mentioned portion.

What I claim is:-

1. A regenerator comprising a chamber and checker bricks therein arranged end to end ineach of a plurality of superposed rows, each of said checker bricks being formed with vertical side walls and with vertical cross walls extending between the side walls and spaced apart to form side by side open ended vertical flow passagespcertain of said bricks each having all of its cross walls spaced upwardly from the plane of its lower edges of its side walls, and other bricks each having all but one of its cross walls spaced upwardly from the plane of the lower edges of its side walls and having the lower edge of said one cross wall enlarged to extend between the planes of the upper and lower edges I checker bricks, thus raising the bricks and taking them along when the plate is withdrawn.

of said side walls, each such enlarged cross wall being in superposed relation with similarly enlarged cross walls of bricks in the different superposed rows, and thereby forming part of a vertical division wall between adjacent end to end sections of the regenerator.

2. Aregenerator as specified in claim 1, in which the side walls of the bricks in the top row of checker bricks are below the top of the regenerator chamber, thereby providing a gas space at 10 the top of said chamber, and in which each top row brick having a cross wall enlarged as specified in claim 1, has said cross wall extended upwardly across said gas space, dividing the latter into end to end sections. 3. A regenerator as specified in claim 1, which is adapted for the insertion of checker bricks into, and their removal from the regenerator chamber at one end of the latter, and in which the said enlarged cross wall of each brick having such a wall,- is at the end of said brick remote from the said one end of said chamber.

4. A regenerator as specified in claim 1, which isadapted for the insertion of checker bricks into, and their removal from the regenerator chamber at one end of the latter, and in which the said enlarged cross wall of each brick having such a wall, is at the end of the brick adjacent the said one end of said chamber, and is formed with a recess comprising a portion extending into said cross wall from its outer side, and a portion extending laterally away from the first mentioned portion.
